Implications of RX100 for low end mirrorless

Have you seen the aperture/focal length table in DPreviews preview of the RX100? At a focal length of 43mm (35 mm eqv.) the aperture has closed down to f3.2. A focal length I use very often. Compare this to the 20mm f.7 on a m43 camera and its implications for IQ in low light!
